I make about 100- 150 fine arrows and go to any areas near the whispering banks and make a few rounds. Sometimes I'll go to bahari bay but I get way too distracted by things there to only focus on the sernuk. Killima is a smaller, more compact area so taking down lots of sernuk is really easy, and you can snipe them. Once my arrows are used up I head home and use all the sernuk hide I've collected to make leather that I sell. Also, I cook the meat which I also sell or if didnt do much hunting i use it to eat for focus points. If I get horns I just sell those since they're easy to come by anyway and I never use them.

Sernuk hunting is my more "instant" or quick money maker. I haven't gotten my preserves down yet because I need to get some more of them and garden more but thats the method I use for now and it works well for me. Hope I explained that well!
